Abstract Moisture-induced damage is the main form of early failure of asphalt pavement in China, and stripping behavior of asphalt film is the first stage of moisture-induced damage in asphalt pavement. To further understand the characteristics of asphalt film stripping behavior, the adhesive work of asphalt-aggregate interface and the cohesive work within asphalt were quantitatively characterized using surface energy theory. Surface energy parameters of different asphalts and aggregates were tested by Young contact angle. The adhesive work of asphalt-aggregate combinations and the cohesive work within different asphalts were calculated under the dry condition and presence of water respectively. The relative magnitudes between adhesive work and cohesive work were compared to infer the potential position of stripping interface. A theoretical proof for stripping interface was provided by the pull-off test. The results showed that cohesive work and adhesive work are both positive without water in asphalt-aggregate system. The cohesive work is significantly less than adhesion work, indicating that the weak interface within asphalt mixture is located inside the asphalt body. With the presence of water, cohesive work and adhesive work are negative, indicating that cohesive failure and adhesive failure tended to be spontaneous in asphalt-aggregate system. The pull-off test shows that, the max breakaway forces between the same asphalt and different aggregates are basically the same on dry condition, and the failure type is determined as cohesive loss C, stripping interface is located inside the asphalt body. When immersed in water, the failure types are interfacial adhesive failure A and mixed failure C/A, and stripping interface is transferred from asphalt body to the asphalt-aggregate interface. This study was conducted based on surface energy theory and pull-off test, providing a theoretical and experimental basis for analyzing the formation mechanism of the stripping phenomenon of asphalt mixture with different conditions and improving the water damage resistance of the mixture.
